Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a clamping and feeding device for a spray pipe drilling equipment. Background Technology

[0002] In drilling operations, stable workpiece clamping and precise feeding are crucial for ensuring machining quality and efficiency. Traditional clamping and feeding devices in drilling equipment often suffer from complex structures, difficult adjustments, insufficient clamping force, or low feeding accuracy, severely impacting machining results and production efficiency. Therefore, developing a novel clamping and feeding device to solve these problems has become a pressing technical challenge for those skilled in the art. Utility Model Content

[0003] To address some of the problems existing in the prior art, this utility model provides a clamping and feeding device for a spray pipe drilling equipment. Through optimized structural design, it achieves rapid clamping and precise feeding of workpieces, thereby improving processing accuracy and efficiency.

[0004] To achieve the above objectives, this utility model provides a clamping and feeding device for a spray pipe drilling equipment, comprising a feeding device body, the feeding device body including a feeding frame, a feeding machine tool mounted on the feeding frame, a bearing plate mounted inside the feeding machine tool, a clamping and feeding mechanism mounted above the bearing plate, a driving structure mounted below the bearing plate, and a connecting rod mounted between the feeding mechanism and the driving structure.

[0005] As a further improvement of this utility model, in order to enable the feeding platform to move smoothly and accurately along the slide rail, and to ensure that the drive structure can accurately transmit power to the feeding platform and achieve precise feeding control, the clamping feeding mechanism includes a feeding slide rail set on the bearing plate, a feeding platform set on the feeding slide rail, a feeding sliding block set between the feeding slide rail and the feeding platform, a quick clamp assembly set on the feeding platform, and one end of the connecting rod connected to the feeding platform.

[0006] As a further improvement of this utility model, in order to effectively prevent the workpiece from shifting or loosening during the clamping process and improve the accuracy and safety of processing, the quick-clamp assembly includes a fixed sleeve with fixed support blocks at both ends. The fixed sleeve is fixed to the feeding platform by the fixed support blocks. A servo motor is provided on one side of the fixed sleeve, and a workpiece clamping cylinder is provided on the fixed sleeve. An inner tube is provided for the connection, and an outer tube is fitted around the inner tube. The diameter of the outer tube at both ends is larger than the diameter at the middle end. A limit groove is provided in the middle of the outer tube, and a limit fixing block is provided on the inner tube inside the limit groove.

[0007] As a further improvement of this utility model, in order to achieve flexible clamping action adjustment so that the chuck can closely fit the workpiece surface, the output end of the workpiece clamping cylinder is connected to a U-shaped connector, the fixed support block is fitted with a connecting block, the bottom two sides of the U-shaped connector are provided with rotating shafts and connected to the connecting block of the fixed support block, and the outer tube is connected to a four-lobed workpiece chuck.

[0008] As a further improvement of this utility model, in order to further enhance the transmission and stability of clamping force, improve the clamping effect of the chuck, and reduce workpiece deformation or damage caused by uneven clamping force, a connecting rib is provided on the U-shaped connector above the rotating shaft, and an installation block is provided inside the U-shaped connector. A groove is provided on the side of the outer tube near the workpiece clamping cylinder, and the installation block is fixed in the groove.

[0009] As a further improvement of this utility model, in order to effectively limit the movement range of the feeding platform, ensure the accuracy and reliability of feeding, and ensure the effective transmission of driving force and the stability of feeding, feeding limiting ribs are provided on both sides inside the feeding slide rail. The driving structure includes a feeding drive motor set below the feeding slide rail. The feeding motor is equipped with a transmission screw. The other end of the connecting rod is connected to the connecting rod.

[0010] When this utility model is in operation, the feeding platform of the clamping feeding mechanism slides on the feeding slide rail via the feeding sliding block. Initially, the feeding platform is located at the starting position of the feeding slide rail, and the four-lobed workpiece chuck is in an unclamped state. The workpiece to be processed is placed on the feeding platform, ensuring that the workpiece is flush with the four-lobed workpiece chuck. When the workpiece clamping cylinder pushes outward, it drives the outer tube to slide. When the outer tube slides, the four-lobed workpiece chuck inside the outer tube gradually closes due to the cooperation of the limiting fixing block and the limiting slide groove, tightly clamping the workpiece. When the four-lobed workpiece chuck is fully closed, the workpiece is firmly fixed on the quick-clamp assembly.

[0011] Start the feed drive motor to make the transmission screw start to rotate. The connecting rod moves along the feed slide rail between the two sets of feed limit ribs, driving the feed platform and the workpiece on it to move towards the processing area. When the feed platform moves to the predetermined position, the drive motor stops working and the feed platform stops stably.

[0012] The beneficial effects of this utility model are reflected in the following aspects:

[0013] Improve machining accuracy:

[0014] By setting up feed slide rails and feed limit ribs, the precise positioning and alignment of the workpiece during the feeding process are ensured, thereby improving the drilling accuracy.

[0015] The quick-clamp assembly is designed to ensure that the workpiece is clamped stably and securely, avoiding errors caused by workpiece shaking or displacement during drilling.

[0016] Improve processing efficiency:

[0017] The drive structure uses a combination of a feed drive motor and a transmission screw, which realizes the automated movement of the feeding platform, reduces the time of manual operation, and improves processing efficiency.

[0018] The quick-release chuck assembly clamps and releases rapidly, reducing workpiece clamping time and further improving processing efficiency.

[0019] Enhance equipment flexibility:

[0020] The design of the connecting rod enables flexible connection and transmission between the feeding platform and the drive structure, facilitating the adjustment of the feeding distance and speed according to different workpiece sizes and processing requirements.

[0021] The four-lobed workpiece chuck design allows the device to be used with workpieces of different shapes and sizes, enhancing the versatility and flexibility of the equipment.

[0022] Improve equipment stability:

[0023] The robust design of the feed frame and feed machine tool provides solid support for the entire clamping and feeding device, ensuring the stability of the equipment during processing.

[0024] The design of the limiting groove and limiting fixing block in the quick clamping assembly effectively prevents excessive tightness or looseness during the clamping process, ensuring stable clamping force. Attached Figure Description

[0036] The quick-clamp assembly 10 includes a fixed sleeve 11, with fixed support blocks 12 at both ends of the fixed sleeve 11. The fixed sleeve 11 is fixed to the feeding platform 8 by the fixed support blocks 12. A servo motor 13 is provided on one side of the fixed sleeve 11.
